Abstract: A control device for operating a machine has a control unit with at least one actuating unit to which actuators and sensors are connected for operating the machine. The control unit has a bus line for transmitting control commands from an operating part to the actuating device. A plug connection between the operating part and the control unit is provided. A monitoring unit monitors an operating signal of the operating part. The monitoring unit triggers a safety function when the operating signal that is a heartbeat of the operating part is absent. Operating states of the operating part are monitored by the monitoring unit. An output signal of the monitoring unit is evaluated in that, when the operating part is switched on, the heartbeat is processed and, when the operating part is switched off, the absence of the heartbeat is ignored.

Abstract: A rope winch has at least one bearing support and a rope drum supported on the at least one bearing support so as to be rotatable about a drive axis. A drive motor and a gear connected to the drive motor are provided, wherein the drive motor drives the rope drum about the drive axis through the gear. At least one sensor that senses a load acting on the rope drum is provided. An exchangeably secured component that is exchangeable without dismounting the at least one bearing support is provided. The at least one sensor is arranged on the exchangeably secured component.

Abstract: In a method for configuring at least one mobile operating unit of at least one control, wherein the at least one operating unit is detachably connectable to the at least one control, wherein the at least one operating unit has a display, a memory, and an input device, the configuration information, required for configuring the at least one operating unit, is transmitted from the at least one control to the at least one operating unit at the time of connecting the at least one operating unit to the at least one control. The configuration information is then utilized in the at least one operating unit. The configuration information saved in the memory can be overwritten by new configuration information received from the control.

Abstract: A cable guide arrangement for a cable winch has a housing to be mounted relative to a cable winch such that a first end of housing faces the cable winch and a second end of the housing faces away from the cable winch. A cable guide channel penetrates the housing and has a closed circumferential wall. The cable guide channel has a longitudinal center axis extending perpendicularly to the first and second ends of the housing. The cable guide channel has open end portions at the first and second ends of the housing, respectively. The open end portion of the guide channel at the second end of the housing widens in a direction away from the cable winch to form an inlet funnel having an edge portion defining a funnel opening. The inlet funnel reduces wear on the cable especially when being pulled at a slant to the center axis through the cable guide arrangement.
